Precision Machinists

High School

For entry-level jobs most employers prefer high school or vocational school graduates. To prepare yourself for a metalworking career, you should take courses in algebra, geometry, mechanical drawing, blueprint reading, machine shop, drafting, and computer applications. If available, classes in electronics and hydraulics can also be useful.

Postsecondary Training

To become a precision machinist, you need to either complete formal training through an apprenticeship or postsecondary program or receive extensive on-the-job training. Apprenticeships generally consist of four to five years of shop training combined with related classroom instruction. During shop work, apprentices learn filing, dowel fitting, and the operation of various other machine tools. The operation and programming of computer-controlled tools are also covered. Classroom instruction includes industrial math, blueprint reading, precision machining, computer numerical control concepts, machine tool technology, and manufacturing processes.

Increasingly, prospective machinists receive postsecondary training through community or technical school programs. Many training facilities have incorporated a set curriculum established by the National Institute for Metalworking Skills (NIMS). After students complete the established courses and pass performance evaluations and written exams, they receive a formal recognition of competency, a NIMS credential. This designation aids in their job search by confirming their skills and knowledge of the metalworking field.

You can also enter the field directly from high school or vocational school and receive on-the-job training. In this case, newly hired workers are supervised by experienced machinists, training with one machine to another. Trainees usually begin as machine operators. Then, as they show the necessary aptitude, they are given additional training on the machines they are operating. Further instruction in the more technical aspects of machine shop work is obtained through studying manuals and classroom instruction. The amount of progress depends on the skill of the worker.

Certification

Some community and technical colleges offer certificate programs in precision machining, computer-numerical control (CNC) machining technology, and CNC machining operator. For example, John Wood Community College in Quincy, Illinois, offers a precision machining machinist certificate. To earn the certificate, students must complete the following courses: Introduction to Drafting and Blueprint Reading for CAD; Technical Mathematics; Introduction to Manufacturing & Industrial Safety; Precision Machining; Introduction to the Manufacturing Processes; Quality/Continuous Improvement; Introduction to Manufacturing Maintenance; CNC Turning; CNC Milling; and Physical Metallurgy. Certificate programs typically last six months to a year and are available in online, in-person, and hybrid formats. Contact schools in your area for information about available programs.

Other Education or Training

Continuing education seminars, webinars, and other learning opportunities are provided by professional associations (e.g., National Tooling and Machining Association, Precision Machined Products Association, Precision Metalforming Association), unions, and community and technical colleges. Contact these organizations for more information.
